The gate agent and the crew were great to accommodate the barrage of flight changes. Once we were cleared for takeoff the flight was very smooth and the cabin crew as well as the pilots did a fantastic job to ensure timely arrival and that everyone is accommodated.

I received at least 3 emails that that the flight was delayed: by 30min, 12min and then by 1min. Of course the mobile app did not reflect this (in an effort to make things more confusing). Once we boarded it was very very hot inside and the pilot informed us that we'll get cooled as soon as they start the engines.

You literally have to pay for even the basic things, including for seats to recline. Cushion on seats thin and seats don't recline. 5hrs flight and No entertainment, no tv, no radio, no complimentary food...they offered a cup of water.

Flight was fine

It was my first time on Frontier. I did not realize they charged for bags and they charged me $60 at the gate for my carry on. Very annoying. Will avoid in ththe future.

Okay 4.6

Bag fees are crazy!! Also frontier does not participate in TSA pre check. So expect long delays at major airports.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
